There are three primary types of wear:(1) abrasie, in which the harder of the surfaces produces grooes in the softer material,(2) adhesie, in which the softer material is transferred as a thin film onto the harder surface, and (3) fatigue, in which repetitie loading produces subsurface cracks and particles, or sheets of material subsequently delaminate and are lost from the surface.

磨损主要有三种类型：1、研磨，硬质表面在软质材料上造成沟槽；2、粘着，软质材料形成薄膜移覆于硬质物体的表面；3、疲劳，反复负载造成材料表面断裂及颗粒形成，或材料出现层裂并从表面脱落。
